Peripheral nerve stimulators designed to apply electrical stimuli to the peripheral nerves in the wrist to treat nausea and prevent emesis (i.e., vomiting). These stimulators typically consist of a wrist band with an electronic device resembling a watch positioned on the underside of the wrist. The device includes a pulse generator, electrodes, batteries, and controls that are used to deliver low-level electric pulses to the nerves when needed. Antinausea/emesis prevention peripheral nerve stimulators are used to provide relief to people suffering from nausea and/or vomiting. Some of these stimulators are disposable and intended to treat patients suffering from motion sickness, undergoing chemotherapy, recovering from surgery, and by pregnant women for a limited period of time.
